Here's a really inexpensive and clever way to smoothly move your video camera around: Place furniture sliders under each tripod leg. The video above shows this working pretty well in action.

The furniture sliders from Bed Bath & Beyond cost about $20 and glide over linoleum, tile, carpet, and cement. (You can also grab these kinds of sliders on Amazon or hardware stores.)

There's some shakiness in some of the shots, which might be fixed with shorter tripod legs or adding some weight to the tripod. It's still a very clever DIY dolly from Justin Leyba of ImagineNow Entertainment.
